Fig. 4From: Accurate characterization of 99mTc-MDP uptake in extraosseous neoplasm mimicking bone metastasis on whole-body bone scan: contribution of SPECT/CTA 59-year-old man with known scapular osteosarcoma was referred for metastatic work-up. The whole-body scan (a, anterior; b, posterior) showed multiple foci of abnormally increased 99mTc-MDP uptake in the left shoulder, supraclavicular region, chest and abdomen (black arrow). Axial CT (c, e, g, i), and SPECT/ CT images (d, f, h, j) showed that the elevated 99mTc-MDP activity was located in the left shoulder, supraclavicular lymph nodes, pleura, lung, posterior peritoneum and periumbilical subcutaneous tissue (the lesion was missed on WBS due to overlap with the lumbar vertebra) (white arrow)Back to article page
